Chapter 25: What? My teacher is a heavy smoker? That's really great!

Previously, the massive infusion of Yang attribute chakra could cause respiratory alkalosis, but that was too obvious and had a very low success rate, not to mention it wasn't discreet.

Now, after Kenichi improvement, it's possible to diffuse Yang attribute chakra into the air around oneself, worsening others' cancer as they breathe it in.

Therefore, theoretically, Kenichi believes his ninjutsu has the potential to evolve into a wide-range offensive technique.

However, there's no need for that now; he's just curious about the impact of cancer on a Chunin.

"Look here, teacher, the test subject's lungs are already showing early signs of lung cancer," Kenichi excitedly told Orochimaru. As expected, even Chunin, who are humans after all, can't escape the effects of lung cancer.

As long as you're human and need your lungs to breathe, you can't escape the impact of lung cancer.

Maybe early-stage cancer doesn't affect combat ability much, but what about the late stages?

What about the terminal stage?

Kenichi once visited a relative in the oncology department of a hospital. Patients in the late to terminal stages of cancer are very pitiful; their bodies can hardly support movement, and lying down is torture, with severe pain constantly tormenting them.

If his experiment succeeds, the physical condition of the opposing ninja will deteriorate over time, even worsening the longer they stay near him.

"I've read your experiment report; the Extraction Technique has no effect on this disease, right?" Orochimaru noticed the difference in this Chunin, looking at his unaffected lungs and asked curiously.

"Yes, teacher. After all, cancer cells are essentially normal cells produced by their own bodies, not identifiable as external harmful substances," Kenichi nodded.

He had previously asked the medical team to try to cure these cancer patients, but so far, none have been successful. Only early-stage cancer has a certain cure rate, while the mid-stage depends on physical condition.

And there hasn't been a single successful cure for late-stage, let alone terminal-stage.

Of course, this might also be because the ninja world's research on cancer isn't very in-depth.

"Continue, I want to see the late stage you mentioned," Orochimaru urged, somewhat impatiently. This behavior is indeed very similar to that of Hashirama cells.

Kenichi nodded, but by the late stage, the subject is probably close to death, and then there would be no saving him.

Soon, as Kenichi continued to infuse Yang attribute chakra into the lung cancer cells, the Chunin's lungs began to show some abnormal patterns, eventually forming a white, irregular depression on the surface of the lungs.

This is a manifestation of lung cancer cells occupying space, visible to the naked eye, proving the cancer cells are significant.

"It took a long time, Kenichi, you need to improve this," Orochimaru shook his head, then nodded, concerned about the time it took.

It took so long to achieve this effect with continuous infusion of Yang attribute chakra; how could there be so much time on the battlefield to continuously infuse chakra?

It seems this ninjutsu currently has significant limitations, but it's a good choice for assassination.

Like my teacher who loves smoking, Hiruzen Sarutobi.

"I understand, teacher," Kenichi scratched his head. The development of this ninjutsu is indeed challenging, but once overcome, the future achievements will not be small.

But if lung cancer cells can be stimulated by nicotine, what about cancer cells in other body tissues? It's not possible to find them one by one; that would be too troublesome.

And regarding this issue, Kenichi also had an idea. In his previous life, when radiation was first discovered, it was considered divine, even used in radium-based cosmetics.

Of course, later people realized that radiation could cause cancer, and they avoided it.

So, Kenichi's idea was to find those radioactive elements in the ninja world. If he could create nuclear radiation...

After learning about the current progress of the experiment, Orochimaru left, but before leaving, he asked Kenichi to record how long this Chunin could survive and note the symptoms.

Kenichi didn't mind; even if his teacher hadn't mentioned it, he planned to do so, as this was a rare opportunity to use a Chunin as experimental material.

After finishing the research, Kenichi went to eat ramen, this time at Ichiraku Ramen.

Ichiraku Ramen has been open in Konoha for many years, witnessing the growth of many ninjas. Rin Nohara, when she was alive, used to come here to eat ramen with Obito and others.

Kenichi also occasionally comes here to eat because the ramen tastes really good, even if it's more expensive than the place he usually goes to.

Kenichi even thinks the previous ramen shop was cheaper because it didn't taste as good as Ichiraku Ramen.

Just after sitting down, Kenichi noticed a ninja sitting two seats away from him, instantly recognizing him by his distinctive hair.

Kakashi.

Kenichi glanced at Kakashi, who was as usual, but now he often appeared and disappeared mysteriously, making Kenichi think he probably joined the Anbu.

The Fourth Hokage, Minato Namikaze, hoped that the busy missions of the Anbu would help Kakashi recover, and it seems to have had some effect.

"Kamui," Kenichi smacked his lips, the more he thought about it, the more he felt this dōjutsu suited him, but now Kamui was in two people.

Kakashi was approachable, but Obito was not.

Moreover, the complete version of Kamui, with both eyes, and even the same space, made Kenichi think about the times Obito was probably attacked by Kakashi's exploding tags and kunai in Kamui's space.

Thinking this way, Obito seemed quite pitiful, and his love for Kakashi was true, not even taking back his own eyeballs.

Kakashi was expressionless, and Kenichi didn't want to impose, so he just quietly ate his noodles.

By the time he finished, Kakashi had already left.

Kenichi didn't mind and walked home leisurely, picking his teeth with a toothpick.

"Brother Kenichi!" But just a few steps away, Kenichi heard a somewhat headache-inducing voice.

Anko Mitarashi came again.
